Python Script Cron Job

[Supa]

I want to use this command: 'jexec 7 python /scripts/conv2mp4.py' to encode my media in an automated process. Any idea what would happen if it runs the python script when it's already currently running? Would it Cancel the current process?

I tested the command in shell and it executed fine. But it's not working in a cron job.

Put jail cron on work...

Any idea what would happen if it runs the python script when it's already currently running?

I would expect it to launch another instance, which may be harmless or harmful, depending on the contents of the script.

Would it Cancel the current process?

No.

Put jail cron on work...

What does this mean?

I tried creating the cronjob inside the jail... with just "crontab -e"

And using something like this:

Code:

*/5 * * * * flock -n /tmp/conv2mp4.lock /usr/local/bin/python /scripts/conv2mp4.py /media/downloads/encode >/var/log/last_conv2mp4.log 2>&1 

I don't even know if I need flock. I just want it to run when it detects a new file in the folder.

Write some file to determine cron is running. Try to emulate cron user enviroment and permissions if you test it manually.
